New derivatives of spicamycin modified at the fatty acid moieties of the molecule were synthesized and their structure-activity relationships were examined. The antitumor activity was greatly influenced by modification of the fatty acid moieties to tetradecadienoyl or dodecadienoyl analogues exhibiting better antitumor activity against COL-1 human colon cancer xenograft than SPM VIII.
新合成了一系列在分子脂肪酸部分进行了修饰的斯匹卡霉素衍生物,并研究了它们的构效关系。通过对脂肪酸部分进行修饰,将其转化为十四碳二烯酸或十二碳二烯酸类似物,这些衍生物对COL-1人结肠癌异种移植模型的抗肿瘤活性显著优于SPM VIII。
